Anyone having problems in running W7 64bits?

I heard many people have problems....

 

What kind of problems? I haven't experienced any problem with Win7 64-bit. 3 desktops, 1 laptop.

The only thing I saw: my trading platform - RealTick... has some display refresh issues in Win7. Some minor ones.

 

There used to be a shortage of drivers but that seems to have been resolved. Biggest issue would be that it does need more ram and disk than 32 bit so I'd avoid it if I had less than 4G of ram.

 

For example, some people say they install 4Gb ram in W7 64bit but only 3.5GB is available

 

If I install 8GB in my 64bit, how much physical ram will be available for me?

 

Depends... Probably close to 8GB

 

Enclosed is a screenshot from my laptop, which has 8GB RAM and Windows 64-bit. Total available is about 8181MB.

 

How about posting that again right after a reboot and with no applications open.

 

Some people said they installed 8GB ram in W7 64bits, but only 4GB available...

 

It looks completely different from 32 bits...is it from "system" or task manager or a separate software?
